边坡稳定分析概率统计法
probabilistic method for slope stability analysis
b一anPo wend一ng fenx一gallO tongJlfo边坡稳定分析概率统计法(probabilistie met-hod for slope Stability analysis)在考虑试验及调查统计的不确定性的前提下，应用概率论和数理统计学，采用具有不确定性模型的可靠性分析，以边坡工程的破坏概率或可靠性作为评价边坡稳定性指标的一种方法。对边坡结构系统来说，在矿山服务期限内，出现抗滑力小于滑动力情况的概率称为破坏概率，即边坡破坏概率几可定义为安全系数小于1的概率。故边坡的可靠性R值可表示为尺一1一几。在露天矿边坡设计中，允许边坡有一定的破坏概率，在拟定相应防护措施，采取对策，取用一定风险系数，进行经济分析基础上，最后根据所得破坏概率与露天矿边坡角的关系，按可能接受的破坏概率，选择经济合理的边坡角。通常露天矿边坡允许破坏概率在5%一10%，也有取10%一20%者，要视具体情况而定。 概率统计法在可靠性计算中，常用的分析方法有:(l)精确概率即随机模拟分析法其典型代表为蒙特卡洛(Monte一carlo)模拟法，它是根据边坡安全状态诸条件，通过随机变量抽样模拟，找出安全系数的分布，求其安全系数小于1的破坏概率进行边坡稳定分析。(2)近似概率分析法如根据一特定系数—可靠性指标来确定边坡破坏概率的可靠性指标法。(3)罗森帕路斯(E.Rosen Bleth)法直接根据随机变量的分布特征，近似地估算随机变量函数分布特征。 概率统计法是20世纪70年代逐渐发展起来的，并为各国采矿公司或矿业研究单位所采用的一种新的边坡稳定分析方法。概率统计法适用于边坡工程地质比较清楚情况下。对于精度要求较高的最终边坡，在可靠性计算中宜采用精确概率分析法;台阶边坡可采用近似概率法分析法。 (于润坤)
